Understand whether the manufacturer through the YY/T0287-1996 medical device system certification
Where the system certification of the enterprise in the component procurement has special requirements for quality, and only the strength and with advanced management concepts of medical device manufacturers can be in accordance with the requirements of the state through the system certification, but also only such a company can guarantee the best Only such companies can guarantee the best product quality and the best after-sales service.
2. Check the manufacturer's website
Learn whether the supplier is a professional medical equipment and disinfection equipment manufacturer, or an agent sales as the main body of the ozone sterilizer is only a few self-produced products of the trading company; understand the type and number of users of each ozone sterilizer manufacturer; when possible, in the same industry, to the other ozone sterilizers being used by users to understand their views on the various brands of ozone sterilizers. users to understand their experience and evaluation of various brands of ozone sterilizers.
3. Reasonable selection of the amount of ozone generation
Ozone generation is to determine whether the disinfection of the environment to achieve the desired disinfection effect of the important indicators, ozone generation will make the disinfection is not complete, the ozone generation of excess will make the price of the equipment increased. To get the most cost-effective ozone sterilizer, according to the need to disinfect the volume size of the place and the required level of disinfection, a reasonable choice of ozone generation. To achieve the lowest level of disinfection, the concentration of ozone per cubic meter of disinfection volume should not be less than five milligrams. As the level of disinfection increases, the concentration per unit volume should also increase.
The ozone values currently calibrated on the equipment are based on standard laboratory data tested in the presence of pure oxygen. The actual ozone generation is 0.2-0.375 times the equipment calibration ozone value (according to the user is located in different sea level areas of the corrected value), this is the user in the selection of ozone volume must be considered when the conversion relationship.
4. Reasonable selection of air supply
Selected the correct amount of ozone generation, the air volume has become another important indicator. The size of the air volume is directly related to whether the amount of ozone can be enough to reach the designated space, and can ensure that any point in the disinfection volume can get the required ozone concentration. At present, the minimum ozone disinfection target is the hourly air volume shall not be less than the total volume to be disinfected, if you want to achieve good disinfection, it is recommended to choose the air volume according to the required disinfection of 2-3 times the volume of air volume, and to the manufacturer to choose the size of the requirements of the fan. Because some manufacturers in the amount of ozone generation can meet the design requirements, but often in the design of the air supply volume ignored the main indicators. Not only affect the overall disinfection effect, and the user's money spent in vain.
5. Whether the use of high-frequency power supply
Low-quality ozone generators often only use common common power supply (including transformers), making the ozone output efficiency is extremely low, but because of the cheap price, the user in the purchase only to find that the disinfection effect can not be achieved at all (such instances have been numerous). High-quality ozone generator to use high-frequency power supply, its frequency is usually 10,000 to 20,000 Hz, such ozone generator efficiency is very high, of course, the price will be higher.
6. Whether it has the function of moisture
Ozone sterilizer with moisture-proof function, you can ensure that the production of humid air in a normal working environment, the service life of the equipment compared to the lack of moisture-proof function to be a lot longer, which is very important to the food processing enterprises.
7. Whether the computer to set any switching time function
Ozone disinfection machine is the user every day to use, and in the work of the operator can not be present in the disinfection equipment. Selection of computer-controlled equipment, you can set a one-time arbitrarily need to work several times a day automatic switch-on and automatic shutdown time, saving each time to repeat to do the work. Reduce labor intensity, improve work efficiency.
8. In-depth discussion with the manufacturer
Disinfection volume, ozone concentration and air supply is the choice of ozone sterilizer several key elements, different users have different combinations of elements. With the ozone sterilizer manufacturer to carry out in-depth discussion, to the manufacturer to put forward their own special combination of requirements, must emphasize the use of high-frequency power supply. Then by the manufacturer according to the user to provide a few key elements of the special combination of design, so that you can get the most cost-effective equipment.
9. 3 factors affecting the price of the product
Ozone generation, high-frequency power supply and the amount of air supply is a direct impact on the price of the key factors. The higher the concentration and the larger the air supply, the better the disinfection effect, and the higher the frequency of the power supply, the higher the efficiency of the ozone generator. Users who are to ensure that their products do not appear bacterial contamination exceeding the standard, safe through the health supervision department's inspection, it is recommended to choose a sufficient concentration of ozone generation and air supply volume. This choice of equipment will be more expensive, but compared to the disinfection is not good, the product bacteria exceeded the standard and was ordered by the health supervision department product withdrawal, factory shutdown and rectification, huge fines and the enterprise list on the blacklist, etc., or to be much more cost-effective. After all, the brand value of the enterprise far more than the cost of saving equipment, and a product was withdrawn from the cabinet to pay the price is far more than the cost of saving equipment tens of times.
10. After-sales service requirements
Users must carefully understand the details of each manufacturer's commitment to after-sales service, try not to choose the after-sales service of their products to set limits or no after-sales service producers, otherwise it will affect the normal operation of the user's business production.
Our company has been focusing on many years, high-end manufacturing, excellent quality, affordable price, factory direct sales, after-sales service
